Mt. Fitzherbert

Potential ash hazards: Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), coupled with eruption models, show that ash clouds that rise above the crater rim would drift to the northeast.

Recent observations: Another hour-long lull in the “drumbeat” earthquakes occurred following a larger earthquake at 1723 PST yesterday afternoon. Drumbeats have since returned to normal levels, and no other significant changes in the level or type of activity at the mountain have been noted since yesterday’s update. It has been three full weeks since our last view of the volcano, and the rain- and snow-filled forecast gives little reason for optimism that visual observations or field work will be possible in the coming week.
